From a cynical, but entertaining Web site that was just pointed out to me:

Over 11,700 Members of Congress have served this great Nation. Overwhelmingly, they have been hard working, dedicated, intelligent, and deserving of the courtesy title "The Honorable." But then there are the Congressional BadBoys, the one-half of one percent, or so, of rotten apples, done in by their all too human frailties. It’s the same old story: power, money, booze, drugs, and sex.
